Novel breaker transfer trolley

Abstract

The invention relates to a novel breaker transfer trolley, which comprises a trolley platform, trolley columns and bolts, wherein guide plates and a first mounting plate are arranged at the head side of the trolley platform; a limiting shaft and a second mounting plate are arranged at the tail side of the trolley platform; mounting holes are both arranged in the first mounting plate and the second mounting plate; an operating lever is arranged in each mounting hole; a tension spring is arranged on each operating lever; an upper tray is arranged at the top surfaces of the trolley columns; a lower tray is arranged at the bottom surfaces of the trolley columns; two lifting screw rods are both arranged at two sides of the upper tray; a lifting guide sleeve is arranged between each lifting screw rod and the upper tray; a lifting adjusting nut is arranged on each lifting guide sleeve; a fixed threaded sleeve is arranged between each lifting screw rod and the trolley platform; and two fixed wheels and two steering wheels are respectively arranged at two sides of the bottom of the lower tray. The novel breaker transfer trolley has the advantages of flexible movement, adjustable height, stability and reliability, convenience for operation and labor saving, and is beneficial to improve the working efficiency.

Description

technical field [0001] The invention relates to a novel circuit breaker transfer trolley, which belongs to the technical field of electrical tools. Background technique [0002] During the entire production process of high-voltage switchgear, it is a key issue to ensure that the circuit breaker can be safely and reliably put into the handcart room of the high-voltage switchgear, because the circuit breaker is relatively heavy, and it is difficult to insert the circuit breaker or pull the circuit breaker out of the handcart room. When it is impossible to lift manually, it is necessary to use a circuit breaker transfer trolley to move the circuit breaker to the switch cabinet. [0003] The circuit breaker transfer trolley has the following technical difficulties. First, ensure that the circuit breaker can be fixed when it is transferred. Secondly, the height of the transfer trolley must be consistent with the height of the guide rail in the handcart of the switch cabinet. When...

Problems solved by technology

[0003] The circuit breaker transfer trolley has the following technical difficulties. First, ensure that the circuit breaker can be fixed when it is transferred. Secondly, the height of the transfer trolley must be consistent with the height of the guide rail in the handcart of the switch cabinet. When the circuit breaker is pushed from the transfer trolley, When arriving at the handcart room, the transfer trolley can be fixed, so as to ensure the safety of the circuit breaker and the operator. In addition, when the circuit breaker is put into the handcart room, the transfer trolley can be removed smoothly, so as to ensure the operation of the circuit breaker, so the circuit breaker The circuit breaker transfer trolley must be stable and reliable during production, use and maintenance, and it must be easy to operate and labor-saving. However, it is difficult for the circuit breaker transfer trolley in the prior art to reliably solve the above-mentioned difficulties.
